Those are just three numbers. They have no volume.
Global population was increased
For seismograph A, the lag time is
5 minutes (difference between 6:10 and 6:05)
For seismograph B, the lag time is
15 minutes (difference between 6:25 and 6:10)
Assuming that earthquake waves have a constant velocity during the earthquake, then the seismograph with the shorter lag time is closer to the epicenter. So,
Seismograph is closes to the earthquake's epicenter
Answer: it’s density is less than the water’s density
Explanation:
If something is floating in a liquid, the density is less. If it sinks in liquid, the density is greater than the liquid.
